BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 338,774, dated March30, 1886.

(No model.)

To aZZ whom it may concern.-

Be it known that I, NELsoN P. PooR, of Cleveland, Ouyahoga county, Ohio,have invented a new and useful Improvement in Binding Attachments forSewing-Machines,

of which the following is aspecification.

The nature of my invention is mainly a binder formed with a folderbetween the two guide-scrolls which fold the binding-strip for :o thepurpose of folding the edges of the cloth to be bound.

In the drawings, Figure 1 is a perspective View. Fig. 2 is a plan. Fig.3 is an end View, and Fig. 4 represents the rear side.

My invention is adapted and intended to be used in binding mattresses.

Hitherto the two edges of the upper and lower parts of a mattress havefirst been folded and sewed, and then the binding has been folded overthe edges and sewed on, thus requiring two separate operations insewing.

In the use of my binder the edges of the mattress are folded, and thebinding strip folded over the edges, and all sewed together at oneoperation.

The upper and lower guide-scrolls, a a, are similar to those of anordinary binder in common use. They are provided with a slotted flangeor projection, e, which is attached to the bed-plate of a sewing-machineby a screw through the slot e. Another scroll-guide or folder, c, isformed on the upper scroll-guide, a, to fold the two edges of themattress, while scroll-guides a a fold the binding-strip over 3 5 them,in order that the folded edges of the mattress and the folded strip withwhich they are to be bound may all be sewed together at one operation.

The two edges of the mattress pass between the upper scroll-guide, a,and scroll-guide c, which folds them, and the strip of cloth with whichthey are to be bound passes through opening 8, and is folded over theedges of the mattress by scroll-guides a a.

The opening sfor the binding-strip to enter, 5 instead of being at theend of the binder, is formed by cutting away the rear sides ofscrollguides a a and leaving the front side or remaining part, i, toproject beyond opening 8, to aid in guiding the strip with which thefolded edges of the mattress are to be bound.

I claim as my invention- 1. A binding attachment for sewing machines,formed with scroll-guides a a, for holding the bindingstrip, and withthe lip or guide 0 extending in between them, to form a channel orpassageway for the edges of the cloth to pass through together, and inwhich both edges are turned over in the same direction and foldedtogether, substantially as described.

2. A binding attachment for sewingmachines, formed with scroll-guides aa, having an opening, s, for the binding-strip to enter beyond the frontpart, i, substantially as described.
